Below this you'll see Proc Amp controls that let you adjust the color characteristics of this source. Every
TriCaster video source has independent controls just like this. Of course internal sources, such as Media Players
do not require a Connection Type setting.
Hint: Network sources are selected right in their monitor's titlebar, for quick access.
WHITE BALANCE
The White Balance controls in the Proc Amp group make it easy to quickly achieve a
pleasing color balance.

The U portion of the video signal carries the blue and yellow color information.
Rotate U Offset clockwise to shift the signal toward blue and counter-
clockwise to shift the signal toward yellow.

The V portion of the video signal carries the red and green color information. V
Offset clockwise to shift the signal toward red and counter-clockwise to shift the signal toward green.
To automatically white balance – click and hold the mouse button over the Color (eyedropper) button, and
then slide the pointer over the monitor for the corresponding source. Release the mouse button over a part
of the image that should be white.
LIVEMATTE AND CROP
The Input Configuration panel has a second tabbed pane labeled LiveMatte and Crop. This tab contains settings
for TriCaster's powerful realtime keying feature – LiveMatte. Every video source has similar controls and can
optionally be keyed, then displayed over other content.
Using LiveMatte is easy. Click on the Pick Color
button in the Matte section of the panel, and keep
the mouse button depressed.
Drag the eye-dropper pointer over the green
background in the DDR's monitor, and then
release it. This establishes the primary key Color, and turns the Enable
LiveMatte switch on.
Adjust the Tolerance slider value higher or lower to include more or less of
the key color in the matte (transparent region).
